| Outline of Final Research Achievements |
Various investigations with a goal of establishing the mix design of concrete considering reasonably segregation and drying shrinkage were conducted. Regarding segregation, the mechanism of segregation occurring during slump test and cylinder penetration test, the effects of materials and mix design on segregation degree of concrete and the effect of segregation degree on various properties of concrete in structures were clarified. Regarding drying shrinkage, the data for various types of cement to input into the prediction equation of drying shrinkage based on composite model were prepared. The effect of external environment on drying shrinkage and the effect of shrinkage crack width on impression were also clarified.
